Wine from rice is of Japanese Asian origins (5)
I believe the answer is:
rioja
'wine' is the definition.
(Rioja is an example)
'rice is of japanese asian origins' is the wordplay.
'origins' says to take the initial letters.
The first letters of 'rice is of japanese asian' is 'RIOJA'.
'from' acts as a link.
(Other definitions for rioja that I've seen before include "Wine from northern Spain" , "Open space (ancient Greek)" , "Popular Spanish wine" , "Spanish wine type" , "North Spanish wine" .)
